WINDOW-SCREEN LATCH.

fo all whom t may concern.'

Be it known that I, IVENDELL H. OMLER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in`Window-Screen Latches; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements 'in latches and more particularlyto those which are designed primarily for securing hinged window screensin closed position, the object being to provide an extremely simple andinexpensive device which will be eective in operation and will notinterfere in any manner with proper movement of the window sashes.

An important feature of the present invention is the particular type oflatch and mounting bracket which permits the latch to be mounted on theinner face of one of the vertical side bars of the screen so that thehook, with which it is provided, can be engaged with an eye on theadjacent inner face of the stop strip so that a direct pull is exertedon the screen when the hook is engaged with the eye to tightly bind thescreen against the stop strip.

Another feature of the invention is the provision of the angularlydisposed fingergrip which, when the latch is locked, is disposed midwaybetween adjacent surfaces of the screen and stop strip to providesufficient space between these surfaces to permit convenient grasping ofthe finger grip.

With the foregoing in view, the invention resides in the novel articlehereinafter described and claimed, the description being supplemented bythe accompanying drawtFigure 1 is a perspective view of a latchconstructed lin accordance with my invention, showing the same inoperative position.

Figure 2 is a view similar to Fig. 1 but illustrating the latchreleased.

In the drawing above briefly described, the numeral 1 designates anattaching bracket adapted to be secured by screws 2, to the inner faceof one of the side-bars of the fra-me 3 of a hinged or other windowscreen Il, and in fact the invention may be used on numerous kinds ofclosures other than window screens. The bracket 2 is pro- Serial No.591,133.

vided with a pair of vertically7 spaced bearing ears 5 and a one-piecewire shaft 6 is both slidably and rotatably received in alined openingsin said ears. The upperend of this shaft is bent laterally outward asindicated at 7 and is then bent downwardly to provide a hook bill 8 forengagement with an eye or keeper 9 carried by the window frame or thelike, the lower' end of the bill being preferably directed obliquelyoutward from the shaft to provide a cam nose 10 which causes the screenframe 3 to be forcibly pulled inwardly against its stop strip 11, whenthe shaft 6 is forced downwardly to the position shown in Fig. 1. Inthis connection, it is to be pointed out that the bill of the hook isspaced a distance from the shaft which is less than the thickness of thestop strip so as to prevent it from projecting beyond the inner surfaceof the latter and interfering with the movement of the Window sash. Y

Between the bearing ears 5, the shaft 6 is bowed into the form of alateral loop 12 forming an operating handle or finger-grip disposed in aplane at an acute angle to the plane in which the portions 7 and 8 arelocated. By this angular relation, the handle 12 does not project intothe path of the window sash when the latch is in operative positionshown in Fig. 1. Also, the handle will be in convenient position to beoperated for releasing or applying the latch. That is, it will bedisposed midway between the screen and stop strip and sufficient spacewill be provided on either side thereof to permit convenient grasping.

While in some instances, the handle 12 might strike the upper bearing 5to limit the upward movement of the shaft 6, I prefer to flatten thelower end of said shaft as indicated at 13, thereby forming a stop forco-action with the lower bearing 5 in limiting the upward movement.

While I have shown only one of the latches, it will be understood thatany desired number may be employed and that if one is used on onevertical side vof a closure and another on the other side, they will ofcourse be manufactured in rights and lefts.

Excellent results have been obtained from the details disclosed and theyare therefore preferably followed, but within the scope of A fastenerfor a swinging screen or the like comprising a bearing bracket mountedon the inner face of one of the vertical sidepieces of the screen, avertically disposed shaft journaled in the bearings of said bracket topermit sliding and rotary movement thereof, said shaft having a stop atits lowerend to limit the upward sliding movement and having a portionof its upper end bent to extend at right angles to the inner face of theaforesaid sidepieces and said portion being then bent downwardly to eX-tend in spaced parallelism to the body portion of the shaft, thusforming a hook for engagement with a keeper mounted on the inner face ofthe stop strip which the screen abuts, the bill of said hook beingspaced a distance fromV said shaft less than the thickness of saidstrip, and the extremity of the bill being bent obliquely to form a camnose to draw the screen into tight contact with said strip, theintermediate portion of said shaft being bent into a loop between itsends to form a finger-grip and the latter being bent at an angle to thehook so as to dispose it substantially midway between the aforesaidinner surfaces of the screen and stop strip to provide suicient space oneither side to permit quick gripping thereof when releasing the device.

In testimony whereof I have hereunto affixed my signature.
